Today software systems are complex, dynamic, distributed, and evolve over time. Multi-agent systems (MASs) are a powerful abstraction to model such systems. Agent programming frameworks support software engineers in transforming these abstractions into concrete distributed applications. Even though there is wide availability of tools for multi-agent(More)
The aim of this paper is to introduce AgentSeeker: a multi-agent platform for indexing local and online textual files, with the semantic contribution of domain specific ontologies. These ontologies describe the application domain and the competences the user is referring to, during the interaction with the platform, namely a query session. AgentSeeker is(More)
technique to face the NP-hard single machine total weighted tardiness scheduling problem in presence of sequence-dependent setup times. The search technique is called Discrete Particle Swarm Optimization (DPSO): differently from previous approaches the proposed DPSO uses a discrete model both for particle position and velocity and a coherent sequence(More)
distributed multi-agent platform for indexing local and online textual files, with the semantic contribution of domain specific ontologies. These ontologies describe the application domain and the competences the user is referring to, during the interaction with the platform, namely a query session. They are used by an Ontology Agent which organizes the(More)
In this paper we present AgentSeeker: a multi-agent platform aimed to index local or online documents, with the support of ontologies which describe the application domain and the competences the user is referring to, during his query session. AgentSeeker is a flexible and scalable solution mainly devoted to enterprise applications where electronic(More)
environment. Herald is suitable for scenarios where the process could be modeled as a tree: starting from the root node the collection of items is distributed along the nodes where they can be processed, forwarded to other nodes, and duplicated if necessary. Herald assigns a specific software agent to each node of the tree which participates into the(More)
work on the field, away from the central headquarters. The main goal of E-Support is to help the field engineers and technicians to access the knowledge base of the company. They will connect to remote servers by using mobile devices in order to get information about vendors, customers, plants, parts and download technical documents. The whole system will(More)
This paper shows the solution provided by D'Appolonia for the support to the maintenance companies and every other enterprise having the need to manage a large amount of electronic documents as textual files, pictures, and cad files. The architecture of the system involves indexing techniques, clustering algorithms and the use of ontologies. The final(More)
Pericles is a design environment for the development of ontologies and interaction protocols integrated in the AgentService framework for Multi-Agent systems. We briefly illustrate the framework, introducing in particular the ontology service which allows AgentService users to clearly represent knowledge bases and message contents. The interaction protocol(More)
